Brief introduction: The G450M laser interferometer system is a two-channel measurement system: one is a 100mm (4-inch) small aperture measurement system, the other is a large aperture plane measurement system. The 100mm aperture system can be used for the measurement of planar and spherical components. The large-caliber plane measuring system is expanded from 100mm to 450mm (18 in.), and the standard plane is transmitted through the standard mirror and the plane reflecting standard mirror. G450S large calibre laser interferometer single optical path system is suitable for in-situ testing of planar components in optical workshop. Main applications: testing the surface shape, optical parallelism and material uniformity of planar optical elements (including glass, metal, ceramics, etc.); Testing the wavefront quality of the collimating system. Spherical optical elements (including all kinds of glass, plastic lens, spherical reflector, optical ring gauge, spherical bearing, etc.), measurement of surface aperture, local deformation, measurement of spherical curvature radius (with grating ruler). Measurement of the surface aperture of planar optical elements (planar mirrors, crystals, ceramics, standard gauge blocks, etc.). Specification parameters: Product model: G450S Measurement method: fissau interference principle Effective optical aperture: 450mm Standard mirror material: fused quartz Light source: wavelength tuned laser (632.8nm), coupled with wavelength phase-shifting interference fringe analysis software; Helium-neon laser (632.8nm) with no interference fringe analysis software Continuous zoom multiple: fixed magnification Optical path switching: switching between alignment (crosshair) and testing (interference field) modes electronically Display mode: real-time display by computer or independent monitor Large aperture plane through standard mirror: PV: better than gap /10 Standard mirror for large aperture plane reflection: PV: better than gap /10 Comprehensive measurement accuracy of large diameter: PV: better than gap /10 Attenuation filter: optional Power supply: ac100-240v 50/60hz Recommended air float platform size (length X width) : 3.5x1.2m
